# These two seds are a pair and the order is load-bearing.
# xen/Makefile:293 has '-Werror=unknown-warning-option'; the
# strip below reduces it to '=unknown-warning-option', and the
# second sed rewrites that to '-Wno-unknown-warning-option'.
# Net effect: clang IGNORES warning flags it does not know
# instead of erroring on them. Xen adds GCC-only flags via
# cc-option-add (e.g. -Wflex-array-member-not-at-end at line
# 404), and cc-option probes without -Werror=..., so clang
# accepts them at probe time and would reject them at compile
# time. Do not 'repair' the strip to preserve -Werror= — that
# re-arms the exact error this exists to disarm.
